I am in search of a cheap receiver to run 6 Aura Bass Shakers. I was looking at an auction on ebay for this receiver (KLH R7000), but I couldn't find out any specs for it. Specifically, from what I've read, I would want the output to go as low as 20Hz. It seems that many of the really inexpensive receivers only go as low as 40Hz. I know it can go 100W per channel, but I haven't been able to find the frequency range. I called KLH customer service, but they were not helpful, as the tech did not have access to a manual. Otherwise, this receiver seems plenty powerful to do what I want it to do. Any thoughts? I realize that similar questions get asked all the time. I did a search online and here, but I'm still stuck.
